Parallel simulation with Cadence

Monady

Hey guys,

I am running a simulation that takes forever to be completed! It has some switched-cap circuits inside and currently I use moderate simulation and ASP is also enabled, with 16 threads and 24 cores. I wonder if there is any option to break the simulation into smaller parts and use several computers to run parallel simulation.

 Thanks

  •  Hi,

    I don't often chime in on simulation issues but I doubt many would be able to help you, your request seems to be too vague.

    1. What sort of simulation are you running, transient, PSS, harmonic balance etc. (you get the picture)

    2. I'm assuming that you are using Spectre as the simulator (APS, not ASP) but which version?

    3. Are the circuit elements all transistors and passives, or do you have any behavioural models?

    4. Is the timestep being reduced to a very small value? This might indicate discontinuities in the models or incorrect component values, or incorrect connectivity even.

    I think that you will need to supply more information, or perhaps file a Case with Cadence Customer Support.

    Best regards,

    Lawrence.
